SLOWDRAW slowness

Redefines FORWARD, BACK, FD, and BK to take longer so that you can see the turtle as it moves (otherwise, the turtle moves as fast as it can). The slowness input controls how long it takes for turtle to complete each movement instruction. The larger the slowness input, the slower the turtle moves.

Running SLOWDRAW 0 restores FORWARD, BACK, FD, and BK to their original speed.

The slowness input must be a nonnegative integer.
